1 Barracuda Backup Vx Virtual Appliance Deployment White Paper

2 DOCUMENT SCOPE This document provides guidance and best practices on designing and deploying Barracuda Backup Vx Virtual Appliance on VMware vsphere and Microsoft Hyper-V platforms. Choosing The Right Platform Barracuda Backup Vx can be deployed in supported VMware vsphere and Microsoft Hyper-V environments.a number of factors must be considered before deploying Barracuda Backup Vx in a virtual environment: Barracuda Backup utilizes memory (RAM) for database queries during backup, restore, and offsite replication. For this reason, Barracuda highly recommends following the recommended minimum resources for memory in the Sizing section below. Barracuda uses CPU resources for hashing blocks during deduplication, compression for offsite replication, and rehydration of data during restoration. It is imperative that the recommended number of cores are allocated for the virtual appliance, based on the Sizing section below. At minimum, memory resources should be dedicated (reserved). It is also recommended that CPU resources be dedicated to Barracuda Backup Vx and not shared with other virtual machines on the host. This aligns with VMware and Microsoft s recommendations for virtualized Microsoft Exchange Server and SQL Server implementations. Other system components such as network and storage need to be sized accordingly to prevent becoming a bottleneck. A separate data store or separate storage server and environment from the production environment is recommend for use with Barracuda Backup Vx due to disk I/O constraints. It is important not to use snapshots on Barracuda Backup Vx. Even if data is not being replicated to the Barracuda Cloud Storage, configuration data is still sent to Barracuda so the unit can be managed. Reverting to a previous state using snapshots can potentially cause loss of data and unit corruption. Independent disks are the default selection and highly recommended to avoid snapshots. SIZING & RECOMMENDED MINIMUM RESOURCE ALLOCATION TB PROTECTED* DISK ALLOCATION CPU CORES MEMORY <1TB 1 TB 2 CPU Cores 4 GB 1 TB 2 TB 2 CPU Cores 8 GB 2 3 TB 4 6 TB 4 CPU Cores 16GB 4 5 TB 8 10 TB 8 CPU Cores 32 GB Note: For environments that need to protect more than 4-5 TB of data, contact Barracuda Networks. * TB Protected is the raw amount of data in the protected environment before deduplication and compression. Disk Allocation is the usable disk space available to store backups and account for retention and typical data growth. It is recommended that disk allocation is at least 2x the amount of TB Protected initially. Disk capacity can later be expanded if disk space is an issue. VMware vsphere Deployment Download and extract the Barracuda Backup Vx.zip archive to a location that can be accessed from a machine running vsphere. Launch vsphere Client and click Deploy OVF Template from the File menu: Page 2 of 17

3 The vsphere Client will launch the Deploy OVF Template wizard. Click Browse, navigate to the extracted folder, and locate the Barracuda Backup Vx OVF file. Example, BarracudaBackupService-vm4.2.4-fw x.ovf. Click Next: In the wizard, complete the following: Review appliance information and correct ESX version Accept the Barracuda End User License Agreement Name the appliance and define a location where the virtual machine is to be created Select the datastore where the VMDK file is to be stored (a dedicated datastore is recommended) Select the disk format as Thick Provisioned Lazy Zeroed Review your settings, and then click Finish to deploy the appliance After deployment is complete, locate the appliance within the appropriate datacenter, host, or resource pool. Note: It is recommended that Thick Provision Lazy Zeroed be used for the disk provisioning and Independent (Persistent) for the Mode. These options, chosen by default, are recommended to achieve the best performance from your virtual appliance and to prevent snapshots from occurring. Page 3 of 17

4 ALLOCATE SPACE FOR THE VIRTUAL MACHINE With the virtual machine powered off, right-click the appliance and choose Edit Settings Edit the CPU, Memory, and Hard disk 1 Provisioned Size settings as defined in the Sizing section above. Once the hardware settings have been defined, power on the virtual appliance. Barracuda Backup Vx will be prepared for use. This may take several minutes. Using your keyboard arrows, select Yes to format and partition the additional disk space you provisioned in step 2 above. Page 4 of 17

5 Using your keyboard arrows, select Yes to format and partition the additional disk space you provisioned in step 2 above. Barracuda Backup Vx expands and formats its partition space. Once the formatting has completed, the appliance will reboot and display: Page 5 of 17

6 MICROSOFT HYPER-V DEPLOYMENT Download and extract the Barracuda Backup Vx.zip archive to a location that can be accessed from a machine running Hyper-V. In Hyper-V Manager, right-click your VM host, select Import Virtual Machine, and click Next. Navigate to and select the Hyper-V folder from within the.zip archive that you extracted in step 1. Click Select Folder and then click Next. Select the virtual machine to import and click Next. Page 6 of 17

7 Select the import type as Copy Virtual Machine (create a new unique ID) and click Next Select the default location for configuration files, storage, and network settings for the VHD, or define custom settings. Then click Next and then click Finish. Page 7 of 17

8 Before powering on the virtual machine, right-click on Barracuda Backup Vx, choose Settings, and define the Memory and Processor settings as specified in the Sizing section above. Click on Hard Drive and under Virtual hard disk, click the Edit button. Click Next and choose Expand in the Choose Action section. Then click Next. Specify the size of the virtual hard disk using the settings as specified in the Sizing section above, click Next, and then Finish. Page 8 of 17

9 On the VM Settings window, click Apply and then OK to finish editing the virtual machine. Power on Barracuda Backup Vx. Page 9 of 17

10 Power on Barracuda Backup Vx. Barracuda Backup Vx will be prepared for use. This may take several minutes. Using your keyboard arrows, select Yes to format and partition the additional disk space you provisioned in step 10. Barracuda Backup Vx expands and formats its partition space. Page 10 of 17

11 Once the formatting has completed, the appliance will reboot and display: OPEN FIREWALL PORTS If your Barracuda Backup Vx is located behind a corporate firewall, open the following ports on your firewall to ensure proper operation: 80 TCP & UDP OUT HEALTH MONITORING 443 TCP & UDP OUT HEALTH MONITORING 1194 TCP & UDP OUT CONFIGURATION/ MANAGEMENT 5120 TCP & UDP OUT BARRACUDA BACKUP AGENT TCP & UDP OUT OFFSITE REPLICATION CONFIGURING AND ACTIVATING THE VIRTUAL APPLIANCE Once you deploy Barracuda Backup Vx, you can provision it. You need your Barracuda Vx license token, which you should have received via or from the website when you downloaded the Barracuda Backup Vx package. If not, you can request an evaluation on the Barracuda Networks website at The license token looks similar to ABCDE. On the System Configuration screen, use keyboard arrows to select TCP/ IP Configuration, specify your network settings, and then Save. Use your keyboard arrows to select Licensing, enter the unique token provided to you by Barracuda Networks to activate the Vx appliance, and then Save. Page 11 of 17

12 On the System Configuration screen, use keyboard arrows to select TCP/ IP Configuration, specify your network settings, and then Save. Use your keyboard arrows to select Licensing, enter the unique token provided to you by Barracuda Networks to activate the Vx appliance, and then Save. Type YES and then press Enter to apply the license and provision the virtual machine. Page 12 of 17

13 Wait for Barracuda Backup Vx to be provisioned. This can take several minutes. Once the license has been installed, press Enter to reboot the virtual appliance. Once Barracuda Backup Vx has completed the boot process, verify that both Local and Internet are Up under Network Status. Note: Cloud will go Up once the appliance has been linked (step 7). Refer to the Barracuda TechLibrary article How to Install the Barracuda Backup Appliance and follow the instructions under Link the Appliance and Create a Barracuda Cloud Control Account if you do not already have a Barracuda Cloud Control account.
